PURPOSE:To obtain an unpowered water suction system utilizing solar heat, by utilizing mechanical energy obtained from the evaporation, expantion and contraction of special liquid for the pumping action of water. CONSTITUTION:Freon gas 9 within a heat receiving tank 3 in a solar housing 1 is evaporated and expanded by being subjected to solar energy and therefore, a soft bag 13 is expanded so that water in an operating tank 5 is raised to a control tank 23 through a check valve 21 and a riser 17. Water is overflown when the control tank 23 is full, and therefore, serves as cooling water for cooling and condensating the gas of special liquid 9, externally, so that the soft bag 13 is contracted, thereby ground water is raised through a suction pipe 15. Repeating these steps, the ground water is stored in a storage tank 29. With this arrangement, an unpowered water suction system utilizing solar energy may be obtained. |
